Which sensor type is commonly associated with disease detecting smartphones' diagnostic capability?

• A. Breathalyzer-style sensors
• B. Facial recognition sensors
• C. Microphone sensors
• D. Temperature sensors

Answer: (A)

Breath analysis is a noninvasive way to glimpse metabolic changes that can indicate health issues. Breathalyzer-style sensors detect volatile organic compounds in exhaled air, turning interactions with those gases into signals the phone can read. Many diseases leave specific biomarker patterns in breath, so these sensors let a smartphone provide quick, indicative readings without drawing blood or using bulky equipment. That’s why this sensor type is most closely associated with disease-detecting capabilities in smartphone diagnostics. Other sensors mentioned don’t fit as neatly. Facial recognition sensors are about identifying people, not detecting disease. Microphone sensors could, in theory, analyze voices or cough sounds, but they’re not standard diagnostic tools built into smartphones. Temperature sensors relate to fever but aren’t a universal, well-established method for smartphone-based diagnostics.
